Why do things happen in our lives the way they do and not otherwise? How can we create the causes for happiness? In the Buddhist practice of mental training, we find the answers to these questions: among other things, it involves overcoming our self-centeredness and developing an attitude of loving appreciation towards others in its place. This, in turn, leads us to a way of acting that naturally guides us away from suffering and towards happiness - in short, generating good karma. In her commentary on one of the great Buddhist poems, The Wheel of Sharp Weapons, Thubten Chodron clearly and practically demonstrates how to eliminate the causes of restlessness, fear, and depression, and create the causes for joyful liberation for ourselves and others.
